Let's be honest though, actually solving this problem is pretty much unachievable given the lack of motivation and interest on the part of the populace, so why bother taking any action to mitigate the problem at all?

I'm really only interested in punchy 3 word concepts like "stop abortion now" or "fix gay people".

The whole idea of investing some effort now so that the world is better off to some unknown extent later is pretty much Socialism. We won the cold war.
